To all whom'z't may concern:

Be it known that L Lnonsnn BRowN, a citizen of the United States, residing; at lVebb City, in the county of Jasper and State of- Missouri, have invented certain new and useful Improvements inSafety Appliances for Automobiles,'of which the following is a specification. V V My invention relates to improvements in apparatus for preventing the operatioirof an automobile by anunauthorized person.

A An important object of the invention, is to provide means for rendering the ignition system of theengine inoperative, and to operate signal, upon the engine being cranked either by hand or by means of a self-starter. r I

A further object of the invention; is to provide apparatus of the above mentioned character, which is convenient to set and reliable in: operation.

Other objects and advantages of the i11 vention will be apparentduring the course of the f ollowingdescription.

In the accompanying drawing forming a part of this specification, is shown a part side elevation and part diagrammatic view of apparatus embodying the invention.

In'the drawings, wherein for the purpose of illustration is shown a preferred embodiment of myinvention, the numeral 5 designates a support, uponwhich is pivoted an actuating member or hub 6. The actuating member isprovided with a key hole 7 for the reception of the key, not shown, and is adapted to'be-turned by means ofthe key and to be locked in the normal position and the open position.

Pivotallyconnected with the support 5, as shown at 8, is a horizontally 'swingingbar 9, to the lower end of which is pivotally connected a friction pulley 10, as shown at 11. When the bar 9'; has its lower end"swungto the left, the-pulley 10 will contactwith the fly-wheel 12. of the engine and be rotated thereby. The bar 9 has pivotal connection below its pivot 8 with a link or'pitman 13, which is pivotally connected with the lower arm of the actuating member 6. Then the t memb rfi is-t nedthe g t, a shown in the drawing, the pitman 13 will swing the lower end of the bar 9 tothe left, thus bringing the pulley 10 in contactwith the periphery .Of the fly-wheel l2.

Extending longitudinally ,ofith'e bar 9 and slidingv in guides l-l carriedthereby is a reciprocatory rod 15, the lowerend of which is preferably provided with a roller 16, e011- tacting with a cam 17, which is connected with the pulley l0, for rotation therewith. Having suitable pivotal connection with the upper end of the 1Od115 is a bell crank lever 18, pivoted to an extension 19,-carried by the bar 9. The upstanding arm ofthe bell crank lever 18 contacts with ashoe 20 formed upon areciprocatory rod 21, operating through stationary guides 22, secured to the support 5. This rod is moved to the right bya spring 21, as shown. The rod 21 has suitable pivotalcomiection with a bell crank lever 23, pivoted to thesupport 5, as shown at 2%.

The horizontal arm of the bell crank lever 23 carries ,a contact'25 insulated therefrom and adapted to engage a contact 26 connected with" the support 5 and insulated therefrom. Pivotally connected with the upstanding arm of the hub 6 is apitman or link 27 having pivotal connection with; a bell crank lever 28 which is pivoted upon the support 5, as shown at 29. The bell crank lever 28 carries a contact 30, which is insulated therefrom andis adaptedto engage a contact 31 secured to the support5 and insulated therefrom. The horizontal armof the hub 61 has pivotal connection with a pitman or link 82-, which is pivoted to abell crank lever'33. This bell cranklever swings'upon a pivot 3a. The bellcrank: lever 33 carries a contact 35 which is insulated therefrom and is adapted to engage a contact 36 carried by and insulated from the support 5.

The numeral 37 designates, a' magneto, which is connected in-a' wire'38. One end of this wire'has electrical connection with the contact 31. The contact 30 has electrical connection with a wire 39 which is connected with one pole 40 of a switch 41. This switchcomprises a swinging. contact arm 42, having electrical connection with wire 43. The wire 43 is electrically connected or grounded to the cylinder or, cylinders 44 of the engine. Connected with the spark plug of the engine is a wire 46 having the usual coil 47 connected therein. The wire 46 is connected with the wire 38 at the point 48. Connected with the wire 38 at the point. 49 is a wire 50, having a storage battery 51 connected therein. The wire has a wire 52 connected therewith, at the point 53 and the wire 52 is connected with the contact 35. The contact 36 has connection with a wire 54, connected with the other pole 55 of the switch 41. The wire 50 is connected with the contact 25 and contact 26 is connected with the wire 38, as shown. A bell 56 is connected in the wire 38, as shown. The operation of the apparatus is as follows:

Assuming that the actuating member 6 is in the normal starting position, the contact 30 will then engage contact 31 and contact 35' will engage contact 36. If the contact arm 42 is moved to engage the pole 40 of the switch 41 current can then flow from the magneto 37, through a portion of the wire 38, contact 31, contact 30, wire 39, pole 40, contact arm 42, wire 43, through the cylinder 44, spark plug 45, a portion of wire 46, coil 47, a portion of wire 46, and through a portion of wire 38 back to the opposite pole of the magneto. By throwing the contact arm 42 so that it engages the pole 55 the magneto will be cut out of circuit and current will then flow from the storage battery 51 through a part of wire 50, wire 52, contact 35, contact 36, wire 54, contact 55, contact arm 42, wire 43, cylinder 44, spark plug 45, a portion of wire 46, coil 47 a portion of wire 46, and through a portion of wire 38 back to the opposite pole of the storage battery. In starting the engine, as is well known, the contact arm 42 is first thrown to engage the pole 55 so that current is obtained from the storage battery and after the engine is started the contact arm is swung to engage the pole 40 thus obtaining current from the magneto. This is the usual construction and no further explanation is deemed necessary, other than to state that when the actuating member 6 is swung to the right, to assume the position shown in the drawing, the contact 30 disengages contact 31 and contact 35 disengages contact 36, whereby the magneto and storage battery circuits are opened at those points and current cannot be secured for starting the engine.

l Vhen the actuating member 6 is moved to the position shown in the drawing, the bar 9 has its lower end swung to the left and thereby contacts with the periphery of the fly-wheel. If the engine is now cranked, the flywheel is turned which rotates the pulley 10. The rotation of the pulley 1O revolves the cam 17 causing the rod 15 to move upwardly. This movement of the rod 15 turns the bell crank lever 18 upon its pivot and shifts the rod 21 to the left, swinging the bell crank lever 23 upon this pivot 24 and bringing contact 25 into ongagement with contact 26, thus closing the circuit to cause the bell 56 to ring. In this closed signal circuit current flows from one side of the source of current 51 through a portion of the wire 50, contact 25, contact 26, a portion of the wire 38, bell 56, and a portion of the wire 38 back to the opposite pole of the storage battery 51. It is thus apparent that the bell 56 will be made to intermittently operate or ring.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from'the' spirit of the invention or the scope of thesubjoined claims.
